Aug 28, 2024 · Central retinal artery occlusion (CRAO) is a cause of inner retinal infarction and profound, monocular vision loss, most commonly caused by embolic occlusion of the central retinal artery. It is often considered to be the ocular/retinal equivalent to cerebral ischemic stroke.

Aug 1, 2017 · Central retinal artery occlusion (CRAO) is an ocular emergency. Patients typically present with profound, acute, painless monocular visual loss—with 80% of affected indi­viduals having a final visual acuity of counting fingers or worse.

Nonarteritic central retinal artery occlusion (NA-CRAO) is a medical emergency characterized by a sudden onset of painless, monocular amaurosis due to retinal ischemia.

Mar 8, 2021 · CRAO refers to compromise of blood flow via the central retinal artery to the inner layers of the retina. This may result in infarction of the retina, and when it does, this conforms to the diagnosis of acute ischemic stroke.

Jun 1, 2016 · “Most patients with CRAO require a brain MRI with diffusion-weighted imaging within 24 hours, if the occlusion is detected acutely,” said Dr. Levin. CRAO and other types of sudden monocular vision loss—such as branch retinal arterial occlusion or retinal transient ischemic attack—greatly increase the risk of silent brain infarctions.

Jun 15, 2017 · MRI revealed a punctate acute stroke along the medial aspect of the right central sulcus, and MRA revealed 30% stenosis of the proximal right internal carotid artery secondary to an atherosclerotic plaque.

Feb 1, 2024 · The central retinal artery (CRA) is a branch of the ophthalmic artery (OA). Its occlusion is presents with a sudden onset, painless, monocular severe visual disturbance.

Typical central retinal artery occlusion with cherry-red spot, retinal edema and narrowing of the vessels.

Diffusion weighted imaging hyperintensity (DWI-H) has been described in the retina and optic nerve during acute central retinal artery occlusion (CRAO). We aimed to determine whether DWI-H can be accurately identified on standard brain magnetic resonance imaging (MRI) in non-arteritic CRAO patients at two tertiary academic centers.

Feb 3, 2018 · Acute retinal arterial ischemia, including vascular transient monocular vision loss (TMVL) and branch (BRAO) and central retinal arterial occlusions (CRAO), are ocular and systemic emergencies requiring immediate diagnosis and treatment.
